the EPO does look to go negative after the 12th, nothing too negative, but still should be sufficient enough, NAO and AO stay negative through at least mid january

So far a moat of nothing between 59 and 105. Points south of 59 and up north and northwest of here got an early start…still waiting around here.

Houston Weather Bureau Office was in Downtown Houston.user:null wrote: ↑Mon Jan 01, 2024 11:11 am2023 was the first freeze-free calendar year at IAH (i.e. ever since opened for business in 1969). The official City of Houston records prior to that were taken at another site farther south (not sure if Downtown or Hobby airport, however).Ptarmigan wrote: ↑Mon Jan 01, 2024 9:37 amThe winter of 1930-1931 did not have freezing temperature. January 1930 had a low of 5°F. 1931 did not see freezing temperature. March 1932 had freezing temperatures and it snowed. 1931 and 2023 are years without freezing temperature recorded. Of course, data from the past should be taken with caution.

Still a big gap off to the southwest - hope it fills in.

-EPO is the king of getting cold down here. Need strong ridging over Alaska and the far NW Territories and for that ridge to extend north into the Beaufort Sea.

So very true about the East Pacific Oscillation (EPO). I have seen many cold blasts due to negative EPO.

I completely forgot about this system to be honest, but got some good heavy rain, just keep it moving so that flooding risks stay low

You can see the surface low forming offshore Matagorda Bay, which is helping to enhance rainfall rates at the moment. No flooding expected though as this system is progressive. And rainfall rates are below flash flood criteria.

Finally some steady rain here but only 0.24" so far. That dry wedge to the SW just doesn't want to completely fill-in.
